Sea Shepherds of Pacific Sharks?

Conservation

Palau’s new shark sanctuary covers 600,000 square kilometers of almost all open ocean, making patrolling for outlaws a bit like searching for a needle in a haystack. In addition, Palau is attempting to make its new sanctuary a model for marine conservation for other small island nations, many of which are more water than land. So the eyes of the Pacific, if not the world, are on Palau to set a model. And they’re going to need help – but the big question is from whom?

Environmental History Lessons

Conservation

The sustainability movement has gained some ground in recent years, evidenced by recycling education in elementary schools, green marketing efforts, and green jobs to support new economies. Sometimes this might seem like we’re in a brave new world, but at the same time we are fighting the exact same battles citizens have been pushing along for decades – for better or worse. A recent reading of First Along the River: A Brief History of the US Environmental Movement I had a much better appreciation of where the modern environmental movement has come from and perhaps where we are going.

Happy World Ocean Day. In lieu of an actually post, take a look at this graph, courtesy of Information is Beautiful. I think this is one of those rare items that needs no additional commentary.

Dear Fishermen, Please release mako sharks alive. Thanks, The Management

The world of fisheries management is so full of laws and regulations that it’s no wonder many fishermen feel persecuted by the government. That’s why I was pleasantly surprised to see the National Marine Fisheries Service trying something new.

International research team tracks threatened oceanic whitetip sharks

Oceanic whitetip sharks are considered by many to be a poster-child for shark conservation. Once one of the most abundant species of pelagic sharks on Earth, unregulated overfishing throughout their global range had led to a precipitous decline in their population. In some parts of their range, the species has declined in population by more than 70% in the last few decades. Scientists haven’t been able to find them in significant numbers for many years. One of the few remaining known aggregation sites is Cat Island in the Bahamas, and that’s where an international team of researchers just went to find these animals.

Resolving human-wildlife conflicts through trust, respect, and… humor?

Conservation

At the International Marine Conservation Congress, I attended a workshop focusing on resolution of human-wildlife conflict that was put on by Francine Madden of the Human-Wildlife Conflict Collaboration. Francine explained her strategies for bringing both sides (wolf conservationists and ranchers, fishermen and government managers, etc) to the table for productive negotiations that benefit everyone.

The Global Extinction Crisis – species area relationships, habitat loss, and population dynamics

May 23, 2011June 3, 2011 Andrew Thaler 4 Comments

Conservation, Science

We are in the midst of a global extinction crisis. Biodiversity is in decline as species after species disappear. Some estimates predict that up to 50% of species will be committed to extinction by 2050. Other estimates claim the current rate of extinction may be 10,000 times the background rate. Many ecologists and conservationists have declared the current species decline the sixth great mass extinction.

A recent paper published in the journal Nature argues that our current estimates of species loss are based on a flawed model and tend to overestimate the magnitude of species decline. The paper has received plenty of attention, and has been heavily criticized by ecologists and conservation biologists. The paper is wrong, but it is wrong for the right reasons, and the criticisms it has garnered point to a gaping hole in our understanding of population dynamics.
